To remove the transducer module at this time use the following procedure.a. disconnect wires at connector (8)b. remove the connector from the wiresc. remove four bolts that fasten transducer module (22) to housing (15)d. feed the wires through housing (18) while removing the transducer module. 5. Remove three bolts (12) from inside housing (14). Remove two bolts (13) and remove housing (14). 6. Loosen locknut (15) and remove engine speed sensor (16). 7. Remove seven bolts (17) and remove the transducer module and housing (18). 8. Remove three bolts (19) and cover (20). 9. Remove two bolts (21). Remove transducer module (22) and gasket. 10. Remove lockring (27), seat (25), spring (24), sleeve (23) and lockring (26). 11. Remove three bolts (28) and remove cylinder (29). 12. Remove sleeve (30), piston (31) and valve (32). Remove O-ring seal (33) from sleeve (30). 13. Remove bolts (34) and remove retainer (35). Remove two races and one bearing (not shown).Assemble Rack Actuator Package
1. Lubricate bearing (37) with engine oil. Install race (36), bearing (37), race (36) and retainer (35) on the fuel injection pump camshaft. 2. Lubricate O-ring seal (33) with engine oil and install on sleeve (30). Install sleeve (32) and piston (31) into sleeve (33). 3. Install sleeve (30) into cylinder (29).4. Install lockring (26), sleeve (23), spring (24), seat (25) and lockring (27) on valve (32). 5. Put cylinder assembly (29) in position on the fuel injection pump housing with piston (31) engaged over fuel injection pump rack (38). Be sure that rack (38) is properly engaged with piston (31). 6. Fasten cylinder (29) to the fuel injection pump housing with three bolts (28). The rack and servo valve (32) must move freely after bolts (28) are tight. 7. Install gasket (39) and transducer module (22) on housing (18). 8. Place wire harness (40) in the slot of the housing. 9. Install cover (20) and bolts (19). 10. Install the gasket and housing (18) on the fuel injection pump housing with seven bolts (17). 11. Install engine speed sensor (16) until it contacts retainer (35). Back the engine speed sensor out (counterclockwise) 180°. This procedure will provide a clearance of .76 mm (.030 in). Tighten locknut (15) to a torque of 13 2 N m (10 1 lb.ft.). 12. Install gasket and housing (14).13. Install the rack position sensor damping seal in housing (14). Install the spring and rack position sensor (11) in housing (14). 14. Connect the rack position sensor wiring connector to the transducer module wiring connector (P8 to J8). Connect the transducer module wiring connector to the control module wiring connector (P5 to J5). 15. Use the following steps to calibrate the rack position sensor:a. Install tool (D) in the fuel injection pump housing and into the slot in the rack.b. Hold the rack against the rack "zero pin" by pushing spring seat (25) on the rack screw towards the rear of the engine.c. Disconnect the PEEC data link connector (P1/J1 connector) from the truck wiring harness and connect it to either tool (A) or tooling (B).e. Turn the ignition switch to the "ON" position without starting the engine.
Do not start the engine with tooling (A) or (B) in place. Engine overspeed will occur.
e. Select "Rack Position Sensor Calibration" from the main menu of tool (C) or (D). See Special Instructions, Form No's. SEHS8742 and/or SEHS8743.f. With the rack held back against "zero pin", adjust the collar on rack position sensor (11) until the bar graph on tooling (A) or (B) is centered and indicates the rack position sensor is calibrated.g. Use tool (C) and tighten rack position sensor locknut to 55 7 N*m (41 5 lb.ft.).h. Recheck the rack position sensor calibration reading on tooling (A) or (B) to insure that the rack position sensor is still in calibration after tightening the locknut.i. Turn off the power to the control module.j. Remove tooling (A) or (B).k. Remove tooling (D) (rack zero pin).l. Disconnect tooling (A) or (B) from the control module (J1 connector). Connect the PEEC data link connector to the truck harness, (J1 to P1 connector). 16. Install bracket (9). Shut off lever assembly pin (42) must rest in yoke (41) of manual shut off shaft. 17. Check orientation of shut off lever assembly (43) with the governor servo valve, manual shut off control shaft and the shut off solenoid. 18. Connect wires at connections (8) and position in bracket (9). Wires inside of the housing must be positioned along the top of the housing. 19. Lubricate O-ring seal (44) with engine oil and install on rack solenoid (7). Install rack solenoid (7) in the housing. The lever arm of solenoid (7) must engage with the groove in collar (23). 20. Install gasket and cover (3). Install line (4). Connect the wiring harness and install connectors (5) in the bracket.
